If your goal is to combine CS with business, look into whether your credentials might get you into the Raikes School at UNL. You’d get the MSEP reciprocity discount, and it’s a fantastic program for what you want - you could major in CS while also gaining a very strong background in business. https://raikes.unl.edu/ Of course, you haven’t told us anything about your qualifications so it’s hard to calibrate what’s appropriate to suggest, competitiveness-wise. Raikes is quite competitive to get into.
DePaul is another school in Chicago with strong CS, and it’s Catholic which might appeal to your parents. There are business minors available to non-business undergrads, as well. There’s an honors program if you’re overqualified for general admission.
